I am curious about the words "considering", "given", and "even though", because they seem to help me build sentences, but I don't know how they work.
Some example sentences:
She can speak English quite well, considering that she only started learning it one year ago.
She can speak English quite well, even though she only started learning it one year ago.
I'll let you rewrite the test, given your special circumstances.
I know that conjunctions like "because" can be used to build sentences in a similar way:
I'll let you rewrite the test, because of your special circumstances.
Wikitionary says that considering and given are prepositions. But I know "because" is a conjunction, and wiktionary says that even though is also a conjunction (and not a preposition).
Questions:
1. What is the difference between how prepositions ("considering", "given") are building these sentences, versus the conjunctions ("because", "even though")?
2. Can many other verbs (other than "to consider" and "to give") be made into prepositions?
